    • Evaluation of heterogeneous scheduling algorithms for wavefront and tile parallelism in video coding 

      Panagou N., Koziri M., Papadopoulos P.K., Oikonomou P., Tziritas N., Kolomvatsos K., Loukopoulos T., Khan S.U. (2019)
      Video is by far the “biggest” Big Data, stretching network and storage capacity to their limits. To handle the situation, video compression has been an active field of study for many years, producing output of huge commercial ...

    • Heuristics for tile parallelism in HEVC 

      Koziri M., Papadopoulos P.K., Tziritas N., Giachoudis N., Loukopoulos T., Khan S.U., Stamoulis G.I. (2017)
      HEVC has emerged as the new video coding standard promising increased compression ratios compared to its predecessors. This performance improvement comes at a high computational cost. For this reason, HEVC offers three ...

    • On predicting bottlenecks in wavefront parallel video coding using deep neural networks 

      Panagou N., Oikonomou P., Papadopoulos P.K., Koziri M., Loukopoulos T., Iakovidis D. (2019)
      Video coding incurs high computational complexity particularly at the encoder side. For this reason, parallelism is used at the various encoding steps. One of the popular coarse grained parallelization tools offered by ...

    • Performance evaluation of batch encodings in HEVC using slice level parallelism 

      Papadopoulos P., Loukopoulos T., Koziri M.G., Anagnostopoulos I., Tziritas N., Stamoulis G.I. (2016)
      HEVC has emerged as the new video standard to replace H.264/AVC. Although the new standard is able to achieve significantly higher compression ratios compared to the older one, it entails high computational demands. To ...

    • Tile Based Wavefront Parallelism in HEVC 

      Papaioannou G.I., Koziri M.G., Papadopoulos P.K., Loukopoulos T., Anagnostopoulos I. (2020)
      High Efficiency Video Coding (HEVC) was developed to tackle the 4K resolution era, achieving up to 50% more compression efficiency (for the same video quality) compared to its predecessor H.264/AVC. However, this performance ...
